Hi Sepide,

re:

Very good.

re:

OK.

re:
> the dataset i made is TEST/GOES, and the band is BAND: 1 0.65 um VIS Cloud

OK, so it really is the visible channel.

Yes.

re:

I just logged into your account on tormenta and ran the DSSERVE command you 
listed
above for VIS data and the dataset was created with no problems:

<as 'sepide' on tormenta>
cd $MCDATA
dsserve.k ADD NCDF/GOES7VIS NCDF 1 9999 TYPE=IMAGE \"GOES-7 images in netCDF 
format

What problem did you see?

OK.

Question:

- how large of an area do you want to cover over each location?

  This will determine how many lines and elements you need to specify
  in each IMGCOPY invocation.

Example:

Here is an example IMGCOPY invocation that will create an output netCDF
file for GOES-7 VIS data centered over Belem (Brazil?).  The size of
the image will be 300 lines by 600 elements:

<still as 'sepide'>
cd $MCDATA
imgcopy.k TEST/GOES NCDF/GOES7VIS.1 LATLON=-1.38 48.48 SIZE=300 600

This will create the file GOES7VIS0001.nc in your McIDAS working
directory (the value of the MCDATA environment variable).

Comments:

- you must always specify the dataset position number for the output dataset.
  This is the '.1' in the 'NCDF/GOES7VIS.1' of the IMGCOPY invocation.  This
  position number gets encoded into the name of the output file:

  GOES7VIS0001.nc
          ^^^^_ - 0001 <-> .1

- if you don't specify the position number of the image in the input dataset,
  the most recent image in the set will be used.  In the example above, the
  image from 06:31 on 1 Jan 1990 will be used as the input image.

  If you want to specify which input image to use, you can do this either
  by dataset position number or by the image's time.

  Consider:

imglist.k TEST/GOES.ALL
Image file directory listing for:TEST/GOES
 Pos Satellite/         Date       Time      Center   Band(s)
     sensor                                 Lat  Lon
 --- -------------  ------------  --------  ---- ---- ------------
   1  GOES-7         1 JAN 90001  00:31:00    -9  108 1
   2  GOES-7         1 JAN 90001  01:31:00    -9  108 1
   3  GOES-7         1 JAN 90001  02:31:00    -9  108 1
   4  GOES-7         1 JAN 90001  03:31:00    -9  108 1
   5  GOES-7         1 JAN 90001  05:31:00    -9  108 1
   6  GOES-7         1 JAN 90001  06:31:00    -9  108 1
imglist.k: done

  To copy the 01:31 image into the 3rd position of the output dataset,
  you could use either of the following two examples:

imgcopy.k TEST/GOES.2 NCDF/GOES7VIS.3 LATLON=-1.38 48.48 SIZE=300 600

  OR

imgcopy.k TEST/GOES NCDF/GOES7VIS.3 LATLON=-1.38 48.48 SIZE=300 600

  Either invocation will create the file named GOES7VIS0003.nc in your
  McIDAS working directory.

Cheers,

Tom
